Embodiment 1
[0011] A kind of UV-high wear-resistant flow coating topcoat of the present invention is a varnish, wherein the components of the varnish and their weight ratios are: 100% UV resin 60, defoamer 0.5, dispersion Agent 1, Initiator 5, Leveling Agent 1, Wear Resistant Agent 4, Monomer 30. Among the above components: UV resin is trifunctional polyurethane acrylic resin, or difunctional modified epoxy acrylic resin or their mixture, such as those produced by CYTEC, SARTOMER, Changxing, Miki, etc. The anti-wear agent is a modified high-purity, high-hardness inorganic powder, such as Sibelco's minspar10. The monomers are: acrylates, modified acrylates or their mixtures, such as those produced by CYTEC, SARTOMER, Changxing, Miki, etc. The defoaming agent is a silicone-free polymer solution, polyacrylic acid polymer or their mixture, such as BYK055, BYK080A or their mixture produced by BYK. The dispersant is high molecular weight block copolymer solution, modified acrylic block copoly...
Embodiment 2
[0017] Another kind of UV-high wear-resisting flow coating finish paint of the present invention is a matte paint, compared with embodiment 1, only the proportioning of parts by weight is different, the components of the matte paint and the proportioning of parts by weight thereof The ratio is: 100% UV resin 65, defoamer 0.5, dispersant 1, initiator 8, leveling agent 1, matting agent 9, wear agent 3, monomer 20. The matting agent adopts organic modified fumed silica, such as READ2105 produced by American Grace Company or fumed silica, such as matting powder OK500 produced by DEGUSS Company.
Embodiment 3
[0019] Another kind of UV-high wear-resistant flow coating topcoat of the present invention is a varnish. Compared with Example 1, only the proportioning by weight is different. The components and weight ratio of the varnish are: 100% UV resin 70%, defoamer 0.7%, dispersant 0.5%, initiator 4, leveling agent 1, wear agent 2, monomer 25%.
[0020]
[0021] The invention adopts wear-resistant agent and UV resin to improve the wear resistance and surface scratch resistance of the coating topcoat, and the hardness and flexibility are relatively balanced, which improves the noble quality of the wood itself, and the formed paint film structure has good flexibility , Scratch resistant. After use, it can form a beautiful and scratch-resistant protective layer on the surface of wooden furniture, wooden floors and other wooden products, thereby forming a durable protection for the surface of wooden furniture and wooden floors.
